A multi-branching dry-type transformer for frequency conversion and speed control of an ocean platform is designed for various voltages and currents required by drilling operation of an offshore oil platform. An auxiliary side coil adopts the four-section cylinder type and is connected with an external pouring terminal plate by branching from the coil, terminals and mark numbers are matched on the terminal plate, and voltage and current output can be changed by changing connection between the terminals. The transformer comprises a primary side winding, an auxiliary side winding and an iron core, and a device body is assembled by a device body insulator and a lead and integrally arranged in a casing. The transformer has the advantages of being compact in structure, meeting the requirement for effective space of the offshore platform, being multipurpose, achieving voltage adjustment required by a drilling platform and being attractive in appearance, fireproof, fire-retardant and tight in closeness. Wiring is convenient.
Description
Technical field: [0001] The invention relates to a dry-type transformer, in particular to a multi-tap dry-type transformer for frequency conversion and speed regulation on offshore platforms, which is mainly used in the technical field of power transmission and transformation. Background technique: [0002] Dry-type transformers for platform frequency conversion and speed regulation generally adopt resin casting type. This kind of transformer has good electrical performance, moisture resistance and pollution resistance. The windings are cast in molds, with smooth surface and beautiful appearance. In addition, the operating conditions of the transformer on the platform are different from those on the land. There are high ambient temperature, high relative humidity, mold, salt spray, oil mist, and tilt vibration. High corrosion of transformer structural parts should be considered sex. Due to the strict space requirements between the transformer installation and the platform s...
